173035-10-4, 1,3-Dimesityl-4,5-dihydro-1H-imidazol-3-ium chloride is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Pd(OAc)2 (0.110 g, 0.50 mmol) and SIMes.HCl (0.170 g, 0.50 mmol) were dissolved in THF (15 mL). The resulting mixture was heated to 55 C along with magnetic stirring for 2 h. After cooling down the mixture to RT, it was purified on silica-gel column. The resulting orange solution was transferred to the Schlenk tube and the solvent was removed under vacuum. The oily residue was dissolved in CH2Cl2 (5 mL) and water (3-10 mL) was added to remove unreacted SIMes.HCl. Organic phase was separated and hexane (5 mL) was slowly added. After 24 h the product was filtered off and dried in vacuum. Yield: 50%. Crystals suitable for X-ray analysis were obtained by slow evaporation of the CH2Cl2/hexane solution. 1H NMR (500 MHz; CDCl3;TMS): delta=6.92 (s, 8H, ArH), 6.77 (s, 8H, NCH2-NCH2), 2.47 (s, 12H, p-ArCH3), 1.94 (s, 24H, oArCH3) 13C NMR (125 MHz; CDCl3; TMS): delta=170.9 (s, N2C), 137.5 (s, NC), 136.1 (s, o-CCH3), 135.7 (s, p-CCH3), 128.8 (s, CH), 122.4 (s, CH2), 21.25 (s, o-CH3), 18.9 (s, p-CH3) elemental analysis calcd (%) C42H52Cl4N4Pd2: C 52.14, H 5.42, N 5.79; found: C 51.15, H 5.09, N 5.30., 173035-10-4
The synthetic route of 173035-10-4 has been constantly updated, and we look forward to future research findings.
